Myrmekes are giant ant-like creatures that are the size of a full grown German Shepherd and love shiny things, such as gold. They live in enormous anthills with complex winding passageways loaded with stolen loot like gold, weapons, and jewellery. They spray poison, have almost unbreakable back armour, have vicious mandibles and can call on the rest of the nest to aid them, and can quickly swarm even the most skilled fighter. Not something a demigod would like to be up against.
